Glutathione S-transferase T1-1 activity upregulated in transitional cell carcinoma of urinary bladder.

OBJECTIVES: To perform a systematic functional investigation of different glutathione S-transferase (GST) classes, including GST class Theta (GSTT) member GSTT1-1, in transitional cell carcinoma (TCC) and the surrounding normal uroepithelium of the same individuals. Recently, it was suggested that GSTT1-1 might be an important risk modulator for TCC. METHODS: Tumor samples and surrounding normal uroepithelium were obtained from 24 patients with TCC of urinary bladder. The following substrates with differential specificities were used: 1-chloro-2,4-dinitrobenzene for overall GST activity; 7-chloro-4-nitrobenzo-2-oxa-1,3-diazole for GST Alpha; 1,2-dichloro-4-nitro-benzene for GST Mu; 4-vinylpyridine for GST Pi 1-1(GSTP1-1); and 1,2-epoxy-3-(p-nitrophenoxy)propane for GSTT1-1. RESULTS: GSTP1-1 and GSTT1-1 activities were demonstrated in all uroepithelial and TCC samples, and GST Mu activity was detectable in 11 of 24 patients. In the tumor specimens, significant upregulation of all expressed GST subtypes was observed. The mean GSTP1-1 and GSTT1-1 level in TCC was increased 2-fold and 3.6-fold, respectively, compared with the mean level in the normal uroepithelium (P <0.001). Tumor GSTT1-1 activities correlated statistically significantly with the tumor stage (P <0.05). CONCLUSIONS: In tumors and adjacent normal uroepithelium of patients with TCC, three major cytosolic GST classes, Mu, Pi, and Theta, were expressed. Although the GST isoenzyme pattern in TCC was similar to that of the corresponding normal uroepithelium, during cancer progression a clear tendency toward an increase in all the GST subtypes expressed was noted. For the first time, distinct GSTT1-1 activity levels were demonstrated in human uroepithelium, as well as its pronounced upregulation in TCC.

Histopathological evaluation of radical prostatectomy in the treatment of localized prostate cancer.

Incidence of prostate cancer has risen dramatically in the past decade. Radical prostatectomy is indicated in patients who have disease localized to the prostate. The aim of the study is to make histopathological evaluation of radical prostatectomy in the treatment local prostate cancer. Authors analyzed 49 cases of radical prostatectomy due to cancer localized to the prostate in period 1996-2000 in Clinic of Urology in Clinical Center of Serbia, Belgrade. The average age of the patients was 65, 6 years (range 44-76, pick 61-70). The most cases 25 (51%, p < 0.001) we found in pT2a N0M0, in pT2b N1M0 9 (18.36%), in pT3bN0M0 10 (20.4%), in pT3bN1M0 3 (6.12%), in pT4aN0M0 2 (4.08%). Nodal status positive was in 12 cases: 9 (18%) in pT2bN1M0- iliac 3 (right 2, left 1), obturatory 6 (right 1, left 5) and 3 cases in pT3bN1M0-iliac left 1 and obturatory 2 (1 right and 1 left). We found Gleason score 8 in 9 cases (18.36%) in pT2bN1M0 versus 7 cases (14.5%) without nodal metastases. Gleason score 9 we found in 3 cases (6.1%) in pT3bN1M0 versus one case without nodal metastases (difference is not significant). Gleason score 3 was in 6.1%, 4 in 12.2%, 5 in 8.1%, 6 in 16, 3%, 7 in 24.5%. Grade 1 of tumors we found in 9 cases (18%), grade 2 in 11 (22%), grade 3 in 29 (60%). HG PIN was in 18 cases (36.7%), LG PIN in 10 (20.4%). In all cases was elevated PSA: 4-10 mmol/L in 24 pts, 11-20 in 15 pts and > 20 in 10 pts. Radical prostatectomy is most adequate method in surgical treatment cancer localized in the prostate. Pelvic lymphadenectomy is necessary for staging purposes in adenocarcinoma of the prostate. Early detection adenocarcinoma of the prostate is important factor in decreasing rate of death.

Antibodies detected in samples from 21,730 pregnant women.

Although anti-D is still the main cause of HDN, many other antibodies have been implicated. From September 1995 to April 2000,screening for RBC antibodies was performed on samples from 21,730 pregnant women regardless of RhD type. Standard tube and gel methods were used. Anti-D was identified in 254 samples; other antibody specificities were detected in 376 samples, for a total of 630 antibodies. For this study, 522 antibodies were considered clinically significant. The incidence of potentially clinically significant antibodies was 2.4 percent. The majority belonged to the Rh system, followed by anti-M, -Fya, -S, -Jka, and -Jkb. Among antibodies of no clinical significance, the most frequent were anti- H, -Lea, and -P1.

[Tumors of the upper urinary tract: results of conservative surgery].

OBJECTIVE: To determine the results of conservative surgery for upper urinary tract urothelial tumours. PATIENTS AND METHODS: From 1986 to 1997, 352 patients were treated in the Belgrade urology clinic for upper urinary tract urothelial tumour. 54 patients (15.3%) were treated by conservative surgery. The sex ratio was 1.3 men for 1 woman. The mean age was 63 years. In most cases, the tumour was situated in the ureter. Conservative surgery was performed on principle in 60% of patients for a small isolated lesion (solitary low-stage, low-grade tumour). In contrast, in about 40% of cases, conservative surgery was performed by necessity due to the presence of bilateral tumours, a solitary kidney or renal failure related to Balkan nephropathy. The median follow-up was 67.3 months (range: 6 months-14 years). RESULTS: 15.8% of patients developed a local recurrence during the follow-up period. The risk of recurrence was higher when conservative surgery was performed for indications of necessity than when it was performed on principle (21.7% versus 11.8%), but the difference was not statistically significant (c2 test, t test). The stage and grade of differentiation were identified as the most significant predictive factors for the risk of local recurrence. The overall 5-year survival rate was 67% with more favourable results in the case of conservative surgery performed on principle compared conservative surgery by necessity (72% versus 60%). The difference between these results was not statistically significant, but a statistically significant difference was observed for tumour stage and grade (grade III versus grade I and II, pT3 versus pT1, pT2). The 5-year survival probability was 68.5%. Recurrence was most likely to occur during the early postoperative course, as 81.56% occurred during the first 18 months. CONCLUSION: Urothelial tumours can be managed conservatively. However, the risk of recurrence is directly correlated with the tumour stage and grade, with a high level of statistical significance, and with the type of indication for conservative surgery performed, but with no statistically significant difference.

[Comparison of upper urinary tract tumors in the region of Balkan nephropathy with those of other regions of Yugoslavia].

OBJECTIVES: To compare the epidemiological and histological characteristics of upper urinary tract tumours in the region of Balkan endemic nephropathy with those of urothelial tumours observed in other regions. MATERIAL AND METHODS: From 1970 to 1997, 766 patients were treated in the Belgrade Department of Urology for an upper urinary tract tumour. These patients were derived from 3 regions: the region of Balkan endemic nephropathy (BEN), the region of probable Balkan endemic nephropathy (PBEN) and the region without Balkan endemic nephropathy (WBEN). The incidence of tumours in BEN + PBEN patients was 68% versus 32% for WBEN patients. The histological and epidemiological characteristics of the tumours in these three groups were compared. RESULTS: Tumours were more frequent in women in the BEN and PBEN groups (1.2:1 and 1.1:1) than in the WBEN group (0.6:1). The tumour was diagnosed an average of 5 years later in the first 2 groups than in the WBEN group (p < 0.05). The BEN and PBEN groups presented a higher incidence of renal failure (45% and 35%), but especially a much higher incidence of bilateral tumours (13% and 6%) than in the WBEN region (2%). CONCLUSION: Our analysis shows that upper urinary tract tumours depend on geographical factors: the incidence of these tumours is significantly higher in regions of BEN and PBEN, women are more frequently affected, tumours are associated with a high incidence of renal failure, bilateral tumours are more frequent, and tumours are more frequent in older patients. Comparison of the histological and pathological characteristics of the tumours did not reveal any significant difference between these three regions.

[Crimean-Congo hemorrhagic fever].

Crimean-Congo hemorrhagic fever was for the first time recognized in Yugoslavia in 1971. In this paper were presented clinical and laboratory findings of a patient infected with Crimean-Congo hemorrhagic fever in Kosovo in 1999. The disease was manifested with fever, headache, vomiting, myalgia, abdominal pain, pharyngitis, conjuctival injection, diarrhoea, hypotension, gingival bleeding, skin hemorrhages, hematuria, hepatomegaly, splenomegaly, jaundice, thrombocytopenia, prolonged prothrombin and partial thromboplastin time, high serum fibrinogen degradation product, leukocytosis, mild anemia, elevated levels of bilirubin and serum aminotransferases. Diagnosis was set clinically, epidemiologically and supported by serological tests. Supportive management of hypotension, multi-organ failure, coagulation disturbances the patient was of the utmost in the treatment together with the isolation and prophylactic measures.

[The lipodystrophy syndrome and protease inhibitor therapy in HIV infection].

The accumulation of adipose tissue in the dorsocervical region is a typical finding in patients with intensive glycocorticoid function. This finding was described in numerous HIV infected patients. Combined antiretroviral therapy that included a protease inhibitor implied the suggestion that dorsocervical fat pad could be a consequence of protease inhibitor therapy. This is a case report of a patient who developed a similar changes a year after the beginning of protease inhibitor therapy.

[Rhino-orbital zygomycosis].

Zygomycosis is rare but highly invasive fungal infection, with high mortality rate. A 67 years old diabetic man was presented with rhino-ocular form of the disease. Fungal elements invaded the skin and subutaneous facial tissue, with involvement of the nose, paranasal sinuses and orbit. The portal of entry of fungus was through paranasal sinuses, after the tooth extraction. Various clinical manifestations were presented: headache, facial swelling, tenderness over the involved sinuses, unilateral orbital cellulitis with proptosis, facial and orbital pain, black nasal discharge, decreased visual acuity, blindness. Patient was treated surgically and by liposomal amphotericin B. He underwent maxillectomy, ethmoidectomy and sphenoidectomy and orbital exenteration because of the dissemination of the disease into the orbit. The specific diagnosis of the infection was established upon the microscopic demonstration of casual agent in the debridement tissue. Early diagnosis was important in this highly fatal disease. Aggressive surgical debridement, therapy with amphotericin B and correction of underlying metabolic acidosis must be performed. The successful medical therapy in this patient suggests that lipid formulation of amphotericin B should be given, because this antifungal agent performed the best control of the infection with the minimal adverse effects.

[A severe form of falciparum malaria associated with staphylococcal endocarditis].

A case is presented of a patient, aged 56 years, with severe form of imported malaria caused by Plasmodia falciparum. Hyperparasitemia of erythrocytes > 30% was registered, and during the course of the disease CNS dysfunction, severe anemia, acute renal failure, disseminated intravenous coagulation with manifest hemorrhagic syndrome, icterus, enterocolitis, pneumonia and staphylococcal endocarditis were developed Due to hyperparasitemia and numerous complications, antimalarial drugs such as quinidine (1,200 mg/day) and artemether (160 mg/day) were administered parenterally. Infected erythrocytes were exchanged with 2.5 litres of healthy erythrocytes suspension. Hemodialysis was also performed as well as nine-week antistaphylococcal therapy. During the treatment preparation of deplasmated blood, concentrated thrombocytes, fresh frozen plasma, cryoprecipitates, human albumins and immunoglobulins were applied, along with the correction of electrolytic dysbalance, administration of diuretic, cardiotonic, antiarrhythmic, anxiolytic, antipsychotic and antidepressive drugs. Two months after the admission the patient was released from the Clinic in good condition, with normal clinical-laboratory findings.
